Fuel is admitted in timedrelation to the inflow oi air. It is the general object or this invention to I I provide an improved air valve construction which also-directly controls the admissionoi' duel. In

the p'referred constructionfliquid fuel; as gasoline, is admitted through .ports in the E pivotal supports of the air valve members, and the valve Imissionports.
